Some taxonomists have also suggested splitting two additional species off from Vitis rotundifolia, Vitis munsoniana and Vitis popenoei.
It is a dark-red or purple water-soluble pigment found in many redberries including chokeberries (Aronia sp), Saskatoon berries (Amelanchier alnifolia) or different species of grape (for instance Vitis vinifera, or muscadine, Vitis rotundifolia), and also part of the pigments responsible for the petal colors in many flowers.
The native grapes of this region of the southeastern United States are the Muscadine and the Scuppernong.
